Audi bringing matrix 'organic' LED concept to Frankfurt

Audi has announced that it's bringing a new concept to the upcoming Frankfurt motor show in September, and now it is teasing the taillights. They adopt organic light-emitting diode technology, which takes advantage of several benefits. For one, it uses a relatively low amount of electricity, between three and four volts. It's also incredibly thin, made up of two layers, each less than a thousandth of a millimeter thick. It casts no shadows, requires no reflectors or any other elements, and emits very little heat. Plus the lights can be formed into different shapes, opening up new possibilities for designers. This isn't the first time we've seen Audi focus on lighting technology, and in recent years it's showcased matrix LED and matrix laser headlights. The company runs through the history of the evolution of its lighting tech in the video above. We'll have to wait a little longer to find out what the team from Ingolstadt will be putting these new taillights on. Audi presents latest lighting technology at the IAA in Frankfurt - Matrix OLED technology makes its debut in a concept car at the IAA - Light attains a new level of homogeneity - Flat light sources open up new design possibilities Audi is presenting its next step in automotive lighting technology at the IAA in Frankfurt. The new Matrix OLED lights enable a previously unattainable level of lighting homogeneity, opening up further creative opportunities for design. As the leading brand in automotive lighting technology, Audi has systematically developed all aspects of OLED technology over the years. Matrix OLED lights combine high-tech engineering and design ideally – initial projects are currently underway to implement OLED technology in production tail lights. They are being shown for the first time in a concept car at the IAA. OLED is an English acronym for "organic light emitting diode." In each OLED unit, two electrodes – of which at least one must be transparent – incorporate numerous thin layers of organic semiconductor materials. A low DC voltage – between three and four volts – activates the layers, each of which is less than one-thousandth of a millimeter thick, to light them. The color is based on the molecular composition of the light source. In contrast to point light sources – such as LEDs – which are made of semiconductor crystals, OLEDs are flat light sources. Their light attains a new level of homogeneity, and its dimming is continuously variable.

Audi recalling 70k TDI models worldwide over braking problem

Audi is issuing a recall covering some 70,000 vehicles worldwide, due to problems with their brake boosters. According to Automotive News Europe, diesel-powered examples of the A4, A5, A6, A7 and Q7 are all being called back due to this issue.
The report indicates that while the brakes in these vehicles still function, the enhancing power from the booster may fail due to a possible leaky membrane.
All of the affected vehicles are powered by the 3.0-liter TDI turbodiesel V6, and were built between March and December of 2012. It is unclear as of this writing how many of these vehicles are in the States, though remember, US customers are not privy to 3.0 TDI examples of the A4 or A5. Autoblog has reached out to Audi for specific numbers, and we'll update this space when we hear more.

Audi A5 and S5 Sportbacks look slinky for the Paris Motor Show

Following closely on the heels of the updated Audi A5 and S5 refresh, the German automaker introduced the 2017 Audi A5 and S5 Sportback. The vehicles are set for an official debut at the Paris Motor Show next month and share many of the same exterior touches as the regular coupes. Audi's sportback models are not sold in the US. A spokesman from Audi told Autoblog that the automaker is still deciding whether to bring the vehicles to the US. The A5 and S5 Sportback are aimed at drivers that want the same feel as the coupe with the added functionality of a hatchback – think wagon meets sedan. Besides the extra set of doors, there's very little that differentiates the sportback models from the coupes. The new models are built upon Volkswagen's MLB platform, which makes the car roughly 190 pounds lighter than the outgoing model. European customers will be able to choose between two TFSI and three TDI engines for the A5 Sportback. The engines range from a 2.0-liter inline-four that makes 190 horsepower to a 3.0-liter turbocharged diesel V6 putting out 286 hp. The engines can be paired to a six-speed manual transmission, seven-speed S tronic dual-clutch gearbox or an eight-speed tiptronic unit. Front-wheel drive is standard, with all-wheel drive as an available option on two variants. AWD comes standard when opting for the more powerful engines. The vehicles will also feature Audi's new Quattro Ultra all-wheel-drive system that can disconnect the rear wheels to be more fuel efficient. The S5 Sportback is the one enthusiasts will enjoy as it packs a turbocharged 3.0-liter V6 that's good for 354 hp and 369 pound-feet of torque. Audi claims the S5 Sportback, even with the addition of its new doors, will be able to get to 62 mph in 4.7 seconds, which is the same time as its two-door counterpart. In addition to the diesel and gasoline-powered vehicles, the A5 Sportback g-tron will be offered for drivers looking for flexible fuel choices. The g-tron model is powered by a 170-horsepower, 2.0-liter turbocharged-inline-four that can run on Audi e-gas, natural gas or regular gasoline. The exterior design is nearly identical to that of the coupes with Audi's new single frame grille and muscular front end. The rear incorporates a fastback-like design, similar to the one found on the A7, which helps soften the vehicle out – all sport in the front and luxury in the rear.
